Human overpopulation has been a concern for scientists since at least 1798, when Thomas Malthus first published his finding that, without significant and ongoing technological innovation, the human population would almost certainly outstrip the planet’s food supply.]]> 2019-02-21 11:39:22 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333575903 1b asmith005 https://padlet.com/asmith005/z2pfesg5tklk/wish/333575996 Agriculture Domesticated Animals and Genetic Modification

The demand to feed a growing human population has facilitated notable advances in agriculture, which was the first major human innovation to enable our survival as a species. Early agriculture allowed hunter-gatherer cultures to settle an area and cultivate their own food.

Growing populations have to be housed, which means they seek more space to build homes and cities. This often involves clearing forests to make room for urban and suburban development, as well as to provide building materials. Currently, it is estimated that 18 million acres of trees are clear-cut every year.]]> 2019-02-21 11:39:59 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333576076 1d asmith005 https://padlet.com/asmith005/z2pfesg5tklk/wish/333576097 Pollution 

Human activities contribute to air pollution, or the emission of harmful substances into the air. While it can be difficult to understand which pollutants are associated with specific effects on the environment]]> 2019-02-21 11:40:02 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333576097 Source 2 asmith005 https://padlet.com/asmith005/z2pfesg5tklk/wish/333578765 2019-02-21 11:51:18 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333578765 2a asmith005 https://padlet.com/asmith005/z2pfesg5tklk/wish/333579493 Impact Humans Have

While we have a good idea of which activities are causing harm to the ocean, scientists have been less clear on which ones are the most damaging and which regions of the ocean are getting the worst of it. Now, New reasearch has allowed scientists to map the impacts of 19 different types of human activity that have harmed the ocean over a span of five years. ]]> 2019-02-21 13:18:14 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333605023 5c asmith005 https://padlet.com/asmith005/z2pfesg5tklk/wish/333605050 New Research Techniques


The researchers used global-scale data to map the cumulative impacts of human activities between 2008 and 2013, pinpointing which areas are under increasing stress, which areas are experiencing a decrease and which human activities are having the biggest impacts in which areas. They found that nearly two-thirds of the ocean in experiencing an increase in these man-made impacts and climate change is the worst of all, driving the majority of the changes the researchers observed.]]> 2019-02-21 13:18:17 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333605050 5d asmith005 https://padlet.com/asmith005/z2pfesg5tklk/wish/333605065 What’s to Come Next?

Figuring out the kinds of conservation efforts that are most effective is the most important next step for research in the field, Halpern says. New studies may be able to pinpoint areas that are doing well and areas that are not, but it’s not able to provide any information about the management techniques that are affecting these areas.]]> 2019-02-21 13:18:21 UTC https://padlet.com/asmith005/z2pfesg5tklk/wish/333605065
