It is necessary to view the lifeforms of not only present but also the past in order of comparative study.This can provide us the possible results in the future. A small step to make people know about the difficult lives in the future world from simple visualizing data from different sources might improve the present.

Here , some environmental challenging factors has been changed overtime are climate , temperature , water , soil , air , and other abiotic factors.

Global warming trend has been observed since the mid-20century . The greenhouse gases like water vapour, carbon dioxide, methane , chlorofloro carbon, etc

blocks the heat from escaping the atmosphere resulting increase in temperature of earth.

Over the last century, the burning of the fossil fuel like coal and oil has increased the concentration of atmospheric carbon dioxide. This has consequences like:

1. Temperature of the earth is increasing day by day.
2. Increase in temperature of sea water causing evaporation, and influencing the sea lives .https://climate.nasa.gov/faq/53/is-the-ocean-continuing-to-warm/
3. Melting of glaciers and snow caps resulting rise in sea level and

Biological-diversity can be studied from different satellites and sensor used in different resolution for study of biological diversity.

Biological-diversity related spectroscopy data of species distribution :

Biodiversity information : for eg as shown in fig below of US forest canopy and more information can be withdrawn from the link below.

species modeling data provides specific species distribution and environmental data for easy analysis of Biological diversity.

he study about the data can provide us essential information

related to biological-diversity on earth at different locations.

And this study results the difference in the Biological diversity overtime.

1. According to data analysis, difference

2.In soil moisture: It provides the nature of soil that changed over period from soil moisture visualizer as shown in fig below.

In this change , Biological diversity changes from different perspectives as soil has important role in ecosystems.

3.the science of green under observation:

This information leads to changes in the greenness of certain locations providing changes in Biological diversity.

4.The rainfall data :

Rainfall determines the vegetation of certain location and distribution of species according to the habitat.means species diversity is maximum where there is suitable environmental conditions. Changes over it can be a good source to study the Biological-diversity.
