Irrigation has a variety of salts
chemicals from industrial activities,
pesticides, and fertilizers seep into the soil

process by which the productivity of the topsoil decreases, caused by overgrazing and deforestation= desertification

clearing and burning of forests to raise crops/livestock adds dust and smoke to the air = Air pollution

Irrigation has a variety of salts= soil salinization

chemicals from industrial activities,pesticides, and fertilizers seep into the soil= soil pollution

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
