Pd. 2 Human Impacts on Earth to Solve by David Friedman https://padlet.com/david_friedman/u35vm4vnnyo2 What is a problem that people have caused on Earth that you'd like to fix? Find a website with information about the problem, and add a link to it to your post. en-us 2017-05-12 13:01:07 UTC 2017-05-14 23:01:02 UTC hello@padlet.com Over fishing- Chase Dotson 04cdotson https://padlet.com/david_friedman/u35vm4vnnyo2/wish/171477411 Overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life.Many fisheries and/or fishermen are fishing too many fish.  Fish levels are going way down because of over fishing. The collapse of the Atlantic Cod Fishery is one such example of how humans have exploited the planet’s natural resources to the brink of extinction. There are now way more species of fish and marine animals that are in large danger of being extinct because of over fishing. Without better control of these important resources, many of the species which humans depend on for sustenance will become unavailable as a food source. The world must do more to sustainably manage fishing if we’re to address increasing global demand for protein in the coming decades. If the situation doesn’t improve, millions of people may no longer be able to afford fish by 2050. Some factors are, lack of protected areas, illegal fishing, and open access fisheries . we need to limit the amount of fishing and add more protected areas https://www.worldwildlife.org/threats/overfishing

This is a serious problem and needs to be fixed before it is too late. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. If this keeps up the average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century. This is very harmful toward the environment showing that us humans pollute the air so much that it causes the temperature to rise. Us humans need to look toward more environmentally friendly solutions with one being that we need to switch to electric cars, solar panels, and decrease the amount of energy used at home. This will cause less air pollution and lets us have  a chance to stop global warming before it is too late.

There is lots of litter in the ocean, and toxins from land fills effect those who live near them. People who live near land fills don grow as much as those who live away from land fills. The gases released from the litter causes this. Also, when litter gets into our oceans and other bodies of water, it can kill or injure species. The main cause of waste disposal is too much consumption. ]]> 2017-05-12 13:17:10 UTC https://padlet.com/david_friedman/u35vm4vnnyo2/wish/171477752 Ozone Depletion- Jake Werner https://padlet.com/david_friedman/u35vm4vnnyo2/wish/171477781 The Ozone is a layer 18.3 miles above the Earth that protects us from harmful radiation and UV rays produced by the sun. Recently humans on Earth are destroying our most important barrier due to pollution. Since the Ozone is deteriorating the temperature on Earth is getting warmer and warmer since we are getting more exposure to the sun. With more exposure from the sun the ice in arctic zones are melting and destorying the habitat for arctic animals. NASA stated that since 1880 the temperature has gone up by 1.7 degrees.

The level of smog is unsafe for people to live in. This could be prevented if less factories were used, and less pollution happened.

There are many other ways of producing energy such as, solar, wind, ocean, geothermal, biomass, hydroelectric, and hydrogen energy would be cleaner ways of producing energy and new ones could still be discovered.

For Instance, it is made of glass and the glass allows light to come in and warm plants and air inside. But, the glass blocks infrared light which makes the heat from the sun, stay in the greenhouse. Earth's atmosphere does the same exact thing as a greenhouse. For Example, During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing the heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. If the greenhouse effect is too strong then there will be a tremendous amount of global warming. Too much carbon dioxide and other greenhouse gases in the air are making the greenhouse effect stronger. However, there are many ways we can reduce the amount of greenhouse gas emissions. We can use renewable energy. For Example, More than half the electricity in the United States comes from polluting coal-fired power plants. And power plants are the single largest source of heat-trapping gas. Fortunately, the use of alternative energy sources, such as solar, wind, geothermal, and hydro energy, is gaining increased support worldwide. The wind energy produced in Denmark, for example, provides about 10 percent of the country's total energy needs. These methods of energy production emit no greenhouse gases once they are up and running. This will emitt less greenhouse gases and reduce the amount of global warming.

Scientist call this the greenhouse gas effect. Humans have been putting chemicals like car exhaust that gets stuck in out atmosphere and warms up the air.

Starrs : MERCURY IN SEAFOOD https://padlet.com/david_friedman/u35vm4vnnyo2/wish/171478825 Overtime mercury from coal plants and factories has collected in the air and found it's place in the ocean. Fish and other seafood absorbed the mercury into their bloodstreams and it has since spread throughout the massive food web of the ocean. With all of this mercury in seafood, it has become dangerous for humans (or anything) to eat too much of it because mercury is a toxic chemical.

Trees aren't just standing there for nothing, they're producing oxygen during photosynthesis for us. As we exhale, carbon dioxide is released in which trees take in. Without trees, would we breath? We may still be able to, but imagine how hard it would to. Especially with over- population, how scary does that seem? Trees also provide habitats for animals and provide food. Lets stop destroying forests for new homes and agriculture and think about others than just ourselves!!!!

This includes human sewage, animal excrement, and rainwater runoff which has fertilizers from lawns and farms. These fertilizers find their way through river systems into seas which cause coastal ocean zones void of oxygen and therefore aquatic life suffers.

Marine litter washes onto beaches, damages boat motors, gets caught in fishing nets, and impacts marine life/birds. Land litter is everywhere. It increases vehicle accidents and harms plants/animals. Land litter can be lead into the water.

  • An estimated 3.5 million tons of trash resides in the Pacific Ocean.
  • Ground-level ozone has dropped by 11% throughout the United States from 2000 to 2010. There is an overall reduction of 28% in ground-level ozone since 1980.
  • 40% of America’s rivers are too polluted for fishing, swimming, or aquatic life.
To solve this problem many factories have changed their ways of disposing of waste, this has helped but we need more change
