hello there
Andrea's point is probably the answer you're looking for, however, you should keep in mind that many (most?) environmental laws are driven more by politics than by the available data. Scientists do research on any number of topics (environmental or not) that have implications for our society. We (scientists) like to think that policy makers take our data and results into consideration when drafting legislation, but I would say that in my experience this rarely happens. For one, there have rarely been any federal legislators who understand science. Even the few physicians who've gone into politics seem largely to fail to understand very basic tenets of science, or at least they don't often demonstrate it with their political actions. Leaving environmental issues, for example, if politicians took science into account, there would be no discussion in any school district in the country about whether or not evolution should be taught in schools, as there are simply *NO* scientists who are qualified to have an opinion who would suggest it shouldn't. Environmental issues are not really any different.

If the temperatures are increasing in a mountainous region, in order to be sure in that, the evidence can simply be obtained by the vegetation. The mountains tend to be warmer at the lower parts, and as the elevation increases, the temperature decreases. If it is a higher mountain, then we will see that there is certain type of vegetation in the lower parts, above it a belt of another vegetation type, above that one there's usually a belt of grasses, and the highest parts are usually with little to no vegetation. If the temperature increases though, then the vegetation from the bottom will start moving upwards, occupying larger portion, the second layer will move upwards as well, and the grasses will come around the top part of the mountain, with the barren part disappearing from the scene.

Answer and Explanation:
Example of j shaped curve is population that is doubling in size and exponential growth. in j shaped curve, population increases rapidly and exponentially and then stops suddenly to start decreasing when resources are limited
logistic growth and population whose size is approaching the carrying capacity of the environment are examples of S shaped curve. here population increases slowly and then rapidly before it becomes stable as approaching zero growth
Population size that a particular environment can support indefinitely without long-term damage to the environment and carrying capacity
is indicated by K . Here population is maximum and has reached saturation and will no longer increase
