Observations/ concerns in the inviroment.

Question

I am doing a survey to see how much people care about our enviroment for a class when school starts in 2 weeks.

- what are your observations or concerns that you have during this past summer, 2008, concerning the enviroment.

- Besides the temperature got warmer, what else?

anything you've noticed? globally? and locally (and please provide location)

- what are somethings that will happen in the future due to these changes?

thanks.

All organisms depend on their habitats for food, water, shelter, and opportunities to breed and raise young. Climate changes can affect organisms and their habitats in a myriad of ways. In fact, global warming impacts all life on earth, from individual organisms to populations, species, communities, and ecosystems. It can alter behaviors, population sizes, species distributions, plant and animal communities, and ecosystem functions and stability. How strongly different species will be affected varies, depending on differences in their ecology and life history. Species with small population sizes, restricted ranges, and limited ability to move to different habitat will be most at risk. Similarly, different habitats and ecosystems will be impacted differently, with those in coastal, high-latitude, and high-altitude regions most vulnerable.

The ranges of many plants and animals are moving toward the poles and toward higher elevations. For example, the ranges of many British breeding birds were, on average, more than 11 miles farther north in the period from 1988-91 than they were in the period from 1968-72, according to comparisons derived from breeding bird atlases. (British butterflies are also being found farther north.)

Egg-laying, flowering, and spawning are occurring earlier for many species, in some cases disrupting delicate cycles that ensure that insects and other food are available for young animals. For example, Tree Swallows across North America have advanced egg-laying by as many as nine days from 1959 to 1991.

Spring migration is occurring earlier and fall migration later in many species. For example, 25 migratory bird species are arriving in Manitoba, Canada, earlier than they did 63 years ago; only two are arriving later.

Global warming increases droughts in some areas; and spruce budworm outbreaks frequently follow droughts, perhaps because dry weather increases the stress on host trees or allows more spruce budworm eggs to be laid. Spruce budworms can be lethal to spruce trees, and spruce-fir forests are a very important habitat type in the northern hemisphere for a wide variety of plants and animals.

observations?

well, yes, a little improvement here and worst things still happening there. but in the end it;s still getting worst and worst in terms of people doing their part even if these GREEN issues has already been in the "mainstream"
