level questions: Human Impact on Ecosystems

QuestionAnswer
Why is our Increasing Population becoming a Problem in terms of Resources?-For the Population, we need Resources like Food and Water, and Land for the Population to Survive. -This can Pressurise the Environment, especially if the Demand is too High -And as the Countries Develop, the Standard of Living also Increases, so we need more Raw Materials in order to make our Cars, iPhone, and our local College. This Rapidly adds on to the Pressuring the Environment
What can happen in the Future if we keep up this Resourcing Usage?-Simply enough, we will just Run Out as its being used up Faster than its Replenished
How can the Way we use Resources affect the Environment?-Burning Fossil Fuels, for example, can have a Negative Impact as it Pollutes the Air, and can contribute to Climate Change -Biodiversity and Humanity in LIC's may get the Hardest Consequences
What Activities are Responsible for the Land to be Going Down? [Why are we using so much land?]-Mining, Dumping Waste, Farming and Building are Key Contributors to the reason why we haven't got much Land Left to play with
How can the Habitat Destruction be a Negative Impact on Biodiversity?-If the Woodlands were being Cleared off, for Farmland, then Species who rely on Trees will Struggle a lot, and those who rely on Trees as Habitats will have to Migrate away, reducing the Biodiversity.
What is Monoculture? What effects can bring for the Biodiversity?-This is simply Farming just 1 Crop, like Palm Oil -This is very Efficient, but can have Biodiversity go down as Land needs to be Cleared for the Large Fields used for this Process
How can Pollution affect the Biodiversity?-Toxic Chemicals, like Pesticides and Herbicides, and Nuclear Waste can pollute the Soil, Air and Water -Sewage also affects the Lakes, Rivers and Oceans as Plants and Animals don't really want Poisonous Toxins being Absorbed in -Smoke and Gases can Pollute the Air, affecting Growth and Stability of the Ecosystem
How can Hunting affect the Biodiversity?-If Animals are Hunted, their Numbers are Reduced. Shocking -This means they can be Endangered, or even Extinct that can Affect the Food Chain, meaning the Biodiversity will be changed for the Worst
What are Conservation Schemes?-Simply helps the Biodiversity by just keeping the Species or Habitats healthy and Intact
How is Protecting Habitats a Conservation Scheme?-Controlling the Water Level, or Trimming the Trees, or making sure that Deforestation doesn't happen can allow Organisms to live in their Natural Environment
How is Controlling / Preventing the Introduction of Harmful Species a Conservation Scheme?-Allowing Harmful Species to not come in can mean Nothing can Threaten the Biodiversity of the Area. -A Key Example is that Grey Squirrels has came over to Britain, and made the Red Squirrels Population decline Fast
How is Creating Protected Areas for Organisms a Conservation Scheme?-National Parks and Nature Reserves help the Biodiversity as its restricting the Land to be Used up by Humanity -This can be seen in the Land, or even in the Water [Marine Ecosystems]
How is Protecting Organisms in Safe Areas away from their Natural Habitat a Conservation Scheme?-Zoos, for Animals, and Botanical Gardens as well as Seed Banks [Plants] help the Biodiversity as its kept in a Safe Area, away from Hunting and Habitat Destruction -Safe Areas can also be used to Increase the Numbers of a Certain Population, useful for Reintroducing the Species back
