Transcript of Humans Affecting food chains


Hunting not only affects the animal species that is killed, but it can also have a significant negative impact on other animals that depend on their survival. If the animal is pregnant or a mother, their young are left to dead. Hunting can also be stressful. Hunting has taken a toll in making species go extinct. There are laws preventing them from killing the animals on the endangered species list but, there are law breakers.
Population Growth
Our new houses and buildings can affect the animals the we know by destorying their homes and habitats. As we grow, theirs depreciate. It is believed that some of our actions have affected the climate, making it warmer in some parts of the world. That makes the ice melt leaving their ecosystem to suffer.
Accidental
Technology has affected the way that people think and drive. Thousands of animals die every day, because of driving accidents. The smallest of animals matter in the food webs. When we destroy the smallest home, the food web has to find another producer. We tame the animals, take them in and think they'll make good pets for awhile. All we're really doing is secretly killing them. Wild animals are made for the wild and bringing them into the home and changing their eating habits and lifestyle is setting them up for failure when they're released back into the wild.
Hunting
Most humans do not understand the impact they have to the food chains and animals all over the world.
One consequence can be that the species will die out. Every food chain could go extinct. There could be no more animals left in the world, by the time humans actually see the damage we are making it would be too late.
Humans interfere in the food web's of different ecosystems, but animals can't always adapt and evolve fast enough to survive.
Human impact on the environment is inevitable. We may never truly destroy Earth. The planet will always remain and its nature will change and adapt to the conditions. If we destroy the Earth we know as home, it will be rebuilt by nature -- slowly, but surely.
Extinction
If humans don't realize their mistakes before it's too late, then life on earth could diminish. Animals, one after another, could go extinct. My evidence for this is that is has happened before. Dinosaurs and woolly mammoths used to roam Earth, and now their extinct.
Human activities have affected our food webs and ecosystems by knocking out some big competitors out in the biosphere. Humans have killed many species off.
“Throughout human existence we have relied on the oceans – for food, as a waste dump, for recreation, for economic opportunities and so on. However, it’s not only our activities in the marine environment that affect life in the sea – it’s also the things we do on land.
With more than half the world’s population now living within 100 kilometres of the coast, it’s not surprising that our activities are taking their toll. Human impacts have increased along with our rapid population growth, substantial developments in technology and significant changes in land use. Over-fishing, pollution and introduced species are affecting life in the sea.”

Humans
Although many humans do not see the long-term effect on the world, we're all not that bad. We don't mean to kill animals and wipe out species, because eventually that could probably happen to us. Extinction doesn't have to happen. We could try to stop it, but it won't work. Humans don't have the capability of changing.
