Tundra:
Environment:
According to the website "Parliament of Canada" the main impacts of human activity on the Arctic tundra are climate change, changes in biological diversity and the use of toxic substances. Climate change is creating a challenging time for all species in the Arctic. The region is fragile which causes a negative impact on plants and animal species. To adapt to an environment takes millions of years, but with unexpected changes human activity is causing global warming, which causes species to not adapt to the environment. Oil industries and human interactions are also impacting species in the Arctic. Mainly the hunt for fossil fuels has a big impact on damaging the Arctic as it is hard to both work and make pipelines safe because of the permafrost. Native people who live in the north have complained that Caribou herds are getting smaller and their land and water sources are contaminated and polluted. In recent years, development of industries in the Arctic have been greater than before. The result of human activity in this region has had a massive negative impact on this fragile ecosystem.
Economics:
Without a doubt the biggest impacts of humans in the Arctic is by oil and gas industries. Further impacts that occur are hunting, over-fishing and pollution.
People:
The positive impacts that human activity has provided economic wealth through oil and gas which has benefited to grow jobs and industry in the region. Also there learning more about the Arctic and its biodiversity, which helps provide awareness to the world about biodiversity and its fragile nature.

Tropical:
Environment:
The two main negative human impacts in the tropical biome is deforestation and overexploitation. Deforestation has environmentalists worried because of the release of carbon from the machinery and the vegetation. It is supposed that deforestation may perhaps speed up the effect of global warming and change the rainforest climate. It is estimated that nearly 2% of the rainforest is lost annually and that approximately 137 species are lost in this biome per day, including species of plants, animals and insects.
Economic:
Different industries such as agriculture and mining have major impacts on the tropical rainforest, as they take place in big areas of the forest that need to be cleared. During the mining process large areas are cleared and roads are built to access the mine. This significantly impacts different areas because of the loud construction noises and pollution. The soil fertility is only good enough to grow crops for a few years after it has been cleared. Farmers take that as an opportunities to clear more and more forest each year to satisfy the needs of consumers.
People:
The two positives of this is that the human activity has opened up opportunities to discover and implement many different medicines. just about 120 prescription medications today are from plants in the tropical rainforest, about ⅔ of the drugs provided are recognized to have cancer fighting properties, fighting malaria, heart disease, hypertension, bronchitis, diabetes, arthritis and other medications. Human activity has unlocked an extremely vital source of medicine. The second positive is that research has shown that harvesting the renewable and sustainable resources already existing in the rainforests is worth more than the industries currently replacing rainforest habitat. Using natural nuts, fruits, seeds and edible plants currently existing in the rainforest as they naturally occur is worth more than the industries they are being replaced with. This evidence proves that naturally occurring rainforests can provide many of the world’s needs as they stand.

Boreal:
There is major human activity in the boreal forest. These industrial developments are important to the Canadian economy however have big impacts on the boreal forest. These industrial developments include activities such as logging, mining, hydroelectric development, oil and gas projects. Oil and gas projects have big impacts on the landscape and boreal ecosystems, like other industrial developments contained in the boreal forest. Roads, pipelines, seismic lines and open pit mines can disturb and put out of place many wildlife species that rely on large intact landscapes. Among 1995 and 2002, Alberta’s energy sector annually cleared an average of 470 km2 of the provinces boreal forest.
