Renewable resources are those which can be replenished or reproduced at a faster rate. But heavily decrease in the volume of these resources sometimes cannot be compensated.
a. Loss of animal species: Hunting and poaching of animal species has limited the population of endangered species to derive valuables like horns, skins from these animals for human use.
b. Land degradation: Landmass occupied by natural forests and other natural biomes are cleared for human use like agriculture, mining, urban development. These lands are loosing their natural potential and are treated as waste lands.
c. Lower availability of fresh water: Water from water bodies like lakes, rivers, groundwater, ponds are polluted by industrial, agricultural wastes making water unfit for human use. Groundwater are pumped out to maximum amount but the same level cannot be maintained by natural sources of water such as rain, agricultural field irrigation, river or any other means therefore, limiting the level of water in grounds.
Answer:
As we know enzymes are specific for different reactions and The conditions required by an enzyme to function are also specific. An enzyme which works in a basic environment will not be able to function in a acidic environment.
If the pH for a reaction is increased from 2 to 11 then this change will change the active site of the enzymes. As a result, the substrate will not be able to fit into the enzyme and hence the enzyme will not catalyze the reaction.
Plants have a cell wall and chloroplasts; animal cells do not have either
