Which of these is a disadvantage of hydropower?

Fish populations can be impacted if fish cannot migrate upstream past impoundment  

dams to spawning grounds or if they cannot migrate downstream to the ocean. Upstream fish passage can be aided using fish ladders or elevators, or by trapping  

and hauling the fish upstream by truck. Downstream fish passage is aided by

diverting fish from turbine intakes using screens or racks or even underwater lights

and sounds, and by maintaining a minimum spill flow past the turbine.

Hydropower can impact water quality and flow. Hydropower plants can cause low  

dissolved oxygen levels in the water, a problem that is harmful to riparian

(riverbank) habitats and is addressed using various aeration techniques, which  

oxygenate the water. Maintaining minimum flows of water downstream of a  

hydropower installation is also critical for the survival of riparian habitats.

Hydropower plants can be impacted by drought. When water is not available, the  

hydropower plants can't produce electricity.

New hydropower facilities impact the local environment and may compete with other  

uses for the land. Those alternative uses may be more highly valued than electricity

generation. Humans, flora, and fauna may lose their natural habitat.

Hope This Helps!  Have A Nice Day!!

relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
