Answer: The statement is true.
Overgrazing happens when the animals or livestock feed on pasture when there is no vegetation present. Overgrazing has devastating impact on the environment as drought can strike any time and lack of precipitation means that farming in that area will also be impacted. The amount of rain received is not under the control of farmers and when the drought conditions extend the replenishment of pasture will not happen. Lack of precipitation will cause the plants to die and eventually the livestock feeds on the available plants to survive.
Plants, trees or crops help in increasing the amount of rainfall by the process of transpiration which is a process in which plants loose water as vapours during the photosynthesis. This water released by the plants increases the moisture content of air making the air saturated and brings about rainfall.
Pollution is the introduction of contaminants into the natural
environment that cause adverse change. Pollution can take the form of
chemical substances or energy, such as noise, heat or light. Pollutants,
the components of pollution, can be either foreign substances/energies
or naturally occurring contaminants. Pollution is often classed as point
source or nonpoint source pollution.

- Membranes and membrane-bound organelles in eukaryotic cells localize (compartmentalize) intracellular metabolic processes and specific enzymatic reactions. Nuclear membranes act as barriers that prevent the passage of molecules between the nucleus and the cytoplasm. ... The nuclear envelope is filled with nuclear pores.
