Why is it important to remember that people are part of the environment too?

The environment is a basic need for well-being, economic, and healthy prosperity. The environment in which we humans thrive is the source of water, food, minerals, and air, and it comprises the solid, gaseous, and liquid components of the planet. The distinct species of forests, the flora and the fauna associate in a composite manner in the environment and naturally plays an essential role in balancing for the optimal survival of the species.  

However, human activities have resulted in the disturbances, which has caused extinction of wide ranges of both plants and animal species. The forests are cleared, the air and water are getting polluted, and the environment is no more considered secure for the upcoming generation. Thus, it is important for the people to remember that they are the part of environment too as life would not be possible if the environment becomes too much polluted.

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
