Habitat Loss There are three major kinds of habitat loss: Habitat _________________: A bulldozer pushing down trees is the iconic image of _______________________. Other ways that people are directly destroying habitat, include ___________ in ____________, dredging rivers, mowing fields, and ______________ down _____________. ____________________: Much of the remaining terrestrial wildlife habitat in the U.S. has been cut up into fragments by ______________ and _________________. Aquatic species’ habitat has been fragmented by _____________ and water diversions. These fragments of habitat may not be large or connected enough to support species that need a large territory in which to find mates and food. The loss and fragmentation of habitat make it difficult for _______________ species to find places to rest and feed along their migration routes. Habitat ________________: Pollution, invasive species and disruption of ecosystem processes (such as changing the intensity of fires in an ecosystem) are some of the ways habitats can become so ___________________ that they no longer support native wildlife

INVASIVE SPECIES __________________ are plants, or animals that are non-native (or alien) to the ecosystem and _____________ ______________. They can harm to the environment, the economy or even, human health. Species that grow and reproduce quickly, and spread _________________, with potential to cause harm, are given the label of “invasive”. An invasive species does not have to come from another ________________. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake in Wyoming because they compete with native cutthroat trout for habitat.

Characteristics of Invasive Species Reproduce _________________ Able to survive and ____________ to new conditions Few natural ______________, competitors or parasites Very difficult to _________________ once established

Pollution Pollution is currently ________________ all forms of life, both on land and in the water, and contributing to climate change. Any chemical in the wrong place or at the wrong concentration can be considered a pollutant. Transport, industry, construction, extraction, power generation and agroforestry all contribute _______________ to the air, land and water. These chemicals can directly affect biodiversity or lead to chemical imbalances in the environment that ultimately kill individuals, species and habitats.

Population Growth Human populations are growing at an exponential rate, resulting in the problems above. There are more than 7 billion people in the world, and although natural disasters, disease and famines cause massive human mortality, we are getting better at surviving and the population just keeps growing. Human population numbers tripled in the twentieth century and although growth is slowing, one estimate predicts it will take until the twenty-third century for them to level out at around 11 billion
