Science Learning Packet BIO B: Population Ecology, Lesson 3 Science Learning Packet BIO B: Population Ecology, Lesson 3 science learning activities for SPS students during the COVID-19 school closure. Seattle Public Schools is committed to making its online information accessible and usable to all people, regardless of ability or technology. Meeting web accessibility guidelines and standards is an ongoing process that we are consistently working to improve. While Seattle Public Schools endeavors to only post documents optimized for accessibility, due to the nature and complexity of some documents, an accessible version of the document may not be available. In these limited circumstances, the District will provide equally effective alternate access. Due to the COVID-19 closure, teachers were asked to provide packets of home activities. This is not intended to take the place of regular classroom instruction but will help supplement student learning and provide opportunities for student learning while they are absent from school. Assignments are not required or graded. Because of the unprecedented nature of this health crisis and the District’s swift closure, some home activities may not be accessible. If you have difficulty accessing the material or have any questions, please contact your student’s teacher. 3/27/2020 How to use this PowerPoint • Work at your own pace.

Inslee signs range of bills aimed at helping orcas Seattle Times, May 8, 2019 By GENE JOHNSON The Associated Press Washington Gov. Jay Inslee, surrounded by lawmakers, tribal members and others, signs the first of several bills designed to help the Pacific... (Rachel La Corte / The Associated Press) SEATTLE (AP) — Washington Gov. Jay Inslee signed several bills Wednesday designed to help the Pacific Northwest’s endangered orcas, measures that he said gave him hope the species might be saved. The measures include requiring more oil shipments near the San Juan Islands to have tugboat escorts to prevent spills, allowing anglers to catch more walleye and bass that prey on young salmon, and giving state agencies the authority to ban toxic chemicals in consumer goods. Other important parts include improving the state’s ability to enforce permit requirements for work that hardens shorelines, such as by installing bulkheads near homes, and making vessels stay farther away from orcas and go slower when they’re near them. “These bills are helping to improve the ecosystems that sustain both salmon and orcas, quiet the waters in which the orcas hunt and provide them more prey,” Inslee said as he signed the bills in Olympia. “While there will be more to do next session, these bills give me hope that we can protect these iconic species for decades to come.” The legislation grew out of recommendations made by Inslee’s orca recovery task force last fall. The orcas that return every year to the waters between Washington and British Columbia are struggling against toxins that accumulate in their blubber, vessel noise that interferes with their hunting, and, most seriously, a dearth of chinook salmon, their preferred prey. There are just 75 of the killer whales left, and researchers say they’re on the verge of extinction. In December, Inslee, who is running for the Democratic nomination for president, proposed what he described as a “herculean effort” — and $1.1 billion in spending — to help the whales. Much of the money was to go toward protecting and restoring salmon habitat. The Legislature directed about $50 million to some important salmon-restoration efforts, including a dam removal on the Nooksack River and flood-plain work along the Dungeness and Cedar rivers. Lawmakers agreed to pay $750,000 to begin planning for what might happen if four huge dams on the Snake River were breached; conservationists say getting rid of the dams is a crucial step toward bringing back salmon and orcas alike, though it faces steep political opposition in eastern Washington. Lawmakers didn’t give Inslee everything he wanted, though, especially when it came to money. They agreed to spend only $100 million — about one-third of what Inslee asked for — to comply with a federal court order to replace more than 400 culverts that block fish passage by 2030. That makes it unlikely the state will meet the court’s deadline. Conservationists nevertheless celebrated Tuesday. Mindy Roberts, Puget Sound director of the Washington Environmental Council, called the bills Inslee signed “the biggest wins for Puget Sound recovery for over a decade.” Activists and researchers have long known that the threats to the whales are urgent, she said, but it took the deaths of several — and the apparent mourning of one mother, named Tahlequah, who carried her dead calf on her head for 17 days last summer — to penetrate the public consciousness. “The visibility of the plight of the orcas — that’s what got people to act,” Roberts said. “People were talking about it at grocery stores. I heard people talking about it at a wedding — and these were not your typical activists.” The bills include: —Senate Bill 5135 , which gives the Ecology Department the ability to ban certain chemicals, including PCBs and PFAS, in consumer products such as carpets, personal care products, building materials and electronics. Researchers say the chemicals can accumulate in the blubber of whales, posing health risks as the whales burn through their fat as they search for scarce salmon. Toxic-Free Future, a nonprofit advocacy group, said the bill gives Washington the nation’s strongest policy regulating toxic chemicals in products. the number of oil tankers in the area by a factor of Pacific Northwest Orca seven.

  • World Population Day
    World Population Day World Population Day (WPD) is an annual event, observed on July 11 every year, which seeks to raise awareness about global population issues. The event was established by the Governing Council of United Nation Development Programmer (UNDP) in 1989. It was inspired by the public interest on Five Billion Day on July 11, 1987, (approximately the date on which the World’s population reached Five Billion people). Need for Population Stabilization has increasingly become indispensible as population beyond the sustainable limit perpetuate poverty, child labour, school drop-outs, malnutrition, Infant Mortality & Morbidity, Maternal Mortality & Morbidity , proliferation of slums and a host of communicable diseases, besides creating a dangerous imbalance between resource, environment and population. Hence, the efforts towards Population Stabilization must be an integral element of development process in all countries, which is essential for ensuring a higher quality of life for people. As the problem is multifaceted, the solution also demands contribution from multiple departments particularly social welfare, education etc. The national theme of this year’s “World Population Day” is “Chhota Parivar- Sukhi Parivar” Ministry of Health & Family Welfare, GOI takes special initiative in observation of the WPD. Government of Delhi adopts guidelines & celebrates accordingly. The first fortnight (27 th June to 10 th July) is known as “Dampati Sampark Pakhwada” or Mobilization Fortnight wherein Behavioral Charge Communication activities like Health Talk, Focused Group Discussion, Role play, Nukkad Natak are organized in all the districts to enhance the awareness for Modern methods of contraception and adoption of Family Planning and small family norms. Second Fortnight (11 th -24 th July) is known as “Jansankhya Sthirtha Pakhwada” as Population Stabilization Fortnight wherein intensified service provision activities in the form of various NSV/ Tubectomy/ IUCD camps are organized at identified facilities across the state.

  • Bhutan's Ecological Footprint Report 2014
    Bhutan’s Ecological Footprint Report 2014 Gross National Happiness Commission, Royal Government of Bhutan in collaboration with Otago Polytechnic, New Zealand July, 2014 Ecological Footprint of Bhutan and its Regions 6 July, 2014 1 | P a g e Executive Summary This report provides the first step in determining the amount of required data that is currently available so that a detailed Ecological Footprinting (EF) analysis can carried out as and when required. The Ecological Footprint tool has been shown globally to be effective at providing a high level guidance on resource consumption and trends in resource demand. The EF uses consumption data and EF conversions to provide a single unit for all the goods and services consumed and the waste created, by a given population. Until now Bhutan’s EF has not been interrogated in detail. The following project uses two different sources of data to calculate Bhutan’s EF. The first results in an EF presented in local (Bhutan) hectares (bha), the second in global hectares (gha). The EF results of the following project show that Bhutan nationals are using less than half the country’s biocapacity. Of the total EF 70% is in energy land and a following 23% in crop land. The food EF is the largest component, totalling 40%, whilst services is close behind on 37%. The results are also compared to EF calculations for Bhutan provided by the renowned EF consultancy, Global Footprint Network (GFN). GFN also found that Bhutan is living within its biocapacity but there were stark differences with this report as it showed the firewood EF to be more than 50% of the available forested land biocapacity.

  • Report on World Population Day 2015 Celebration
    USAID MCH Program - Health Communication Component Report on World Population Day Celebration Population Mela September 1 and 3, 2015 Rural Support Programmes Network _____________________________________________________________________________________ Report on World Population Day World Population Day has been celebrated every year on July 11 since 1989. In 1968 world leaders proclaimed that individuals have a basic human right to determine freely and responsibly the number and timing of their children. World Population Day was initiated in 1989 when the world population surpassed five billion, marked on July 11, 1987. The UN authorized the event as a vehicle to build an awareness of population issues and the impact they have on development and the environment. Since then, with the United Nations Population Fund's (UNFPA) encouragement, governments, non-governmental organizations, institutions and individuals organize various educational activities to celebrate the annual event. World Population Day aims to increase people’s awareness on various population issues such as the importance of family planning, including gender equality, poverty, maternal health and human rights. The day is celebrated worldwide and the theme of this year's World Population Day is Vulnerable Populations in Emergencies. USAID’s MATERNAL AND CHILD HEALTH PROGRAM USAID has been a stalwart partner to Pakistan. USAID’s current flagship Maternal and Child Health (MCH) Program with its five interrelated components: 1) Family Planning/Reproductive Health (FP/RH); 2) Maternal, Newborn and Child Health (MNCH); 3) Health Communication; 4) Health Commodities and Supply Chain; and 5) Health Systems Strengthening, is an innovative program designed to improve health outcomes of women and children in target areas.

  • World Population Day
    WORLD POPULATION DAY There have always been a lot of problems that human world has had to face, whether it be man-made or natural. Pollution, depleting natural resources and climate change are few of the the major difficulties that we face and must try to resolve. However, the exponentially rising world population still remains to be the biggest challenge. We observe 11 July as World Population Day to bring focus to this problem of overpopulation. an annual event. The main purpose of marking such a day is to bring awareness about the rising global population and problems that arise with overpopulation. The event was first suggested by Dr. Zacharia in his capacity as a demographer at the World Bank. In 1989, the governing council of UNDP (United Nations Developing Program) decided to mark every July 11 as the World Population Day. Countries also use the occasion to spread awareness about family planning, poverty, and human rights. The UN Population Development along with the UNDP closely works with various countries and other agencies to spread the message. They even plan and execute several programs to educate people and help curb global overpopulation. We, humans, have always taken things for granted and same is the case with the resources that we are using without even thinking. Higher the population, higher will be the exploitation of resources. Many states are already facing shortage of electricity this summer. If we are able to control our population, we would be taking a step towards a developed and content country. We should never forget that “The greatest threat to human existence is our own lack of ability to control our own growth”.

WORLD POPULATION DAY THE READING / TAPESCRIPT World Population Day is observed annually on July 11. Its aim is to raise awareness of global population problems. The event started in 1989 in response to the world’s population reaching five billion two years earlier. The United Nations Development Programme created the day and has since set up campaigns to warn us of the dangers of overpopulation. These problems include water shortages, food shortages, increased pollution, poverty and wars over scare resources. On World Population Day, the UN and governments around the world run educational campaigns in schools and local communities. It makes people aware of what we need to do so the world can survive with billions more people. World Population Day focuses on sustainability and how to improve the lives of all people while protecting the Earth’s resources. Overpopulation refers to the point when the Earth does not have enough resources to feed everybody. Overpopulation can exist even in deserts where very few people live if there aren’t enough resources to sustain them. These resources include clean water, food, shelter, and clean air. There are many reasons why the Earth is becoming overpopulated today.
