Feeding the world's growing population is one of the great challenges of the 21st century, particularly in China, which has nearly a quarter of the world's population but a fraction of the cropland. People with homes damaged by extreme weather events are more likely to experience mental health issues such as depression and anxiety even when the damage is relatively minor and does not force them ... They occur in places wherever plants are abundant -- such as the raging fires currently burning in the Brazilian Amazon. Scientists have been researching the effect of precipitation and population size on rising temperatures in cities compared with the surrounding countryside. Scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago -- a time in which the Earth was two to three degrees Celsius warmer than ... With over 7.5 billion of us on Earth, our combined actions also have a big impact on the environment.Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's.

Ronnie and Denise from Dragonfly TV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake.
In this experiment you can discover how maps can be used to show how different animals are distributed in a local environment.
Read more Even though many cities have recycling programs, a lot of trash still ends up in the dump.
A valuable research paper topic can address this question, attempt to prove global warming as a viable concern or debunk it as a "Chicken Little" fear.
Either way, your students will find a spectrum of evidence that supports either view and good research material for their essays.Although paint and gasoline sold today no longer contain lead, soil can have contamination from older sources of lead, such as paint from old…The environment has been a hot button issue for over the last half century.Find out which materials will break down and which materials won't. When you walk on the grass, you are squishing millions of micro-invertebrates!Will the results of this experiment change which products you often buy? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. Just kidding, these animals are too small to squish.They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was.In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of…Water pollution, once thought a vanished concern of the 1970s, is still very much with us, and the groundwater quality of various locations is still of great concern to experts.Student research essays can select water quality as a topic, researching the current extent of water pollution as well as our efforts to overcome it.As long as we are aware of the impact, we can do things as individuals, and working together as groups, to lessen the detrimental impact of billions of people.With our list of environmental science fair project you can explore and understand important topics like air quality, water quality, the effects of climate change, and many others so that you can make informed decisions about caring for our planet.
