**! need 1. coal, a nonrenewable resource, is the most abundant fossil fuel produced in the united states. although environmental laws and modern technologies have reduced the impact on the environment from the production of coal, coal mining continues to disrupt nearby aquatic ecosystems. high concentrations of toxins and heavy metals can be carried as run-off into nearby ponds and streams. how would this affect the sustainability of the aquatic habitat? a) it could kill off any animals, such as fish, that live exclusively in the pond. b) the heavy metals and toxins will only effect the top predators of the food web. c) because heavy metals and toxins are not lethal to plants, it will not effect the habitat. d) the heavy metals and toxins could affect the food web and reduce biodiversity. 2. there are many positive and negative aspects associated with nuclear power. which is a negative aspect associated with nuclear power? a) nuclear power is a renewable energy source. b) nuclear power does not contribute to the greenhouse effect. c) it is more efficient than other methods of energy production. d) exposure to radiation can lead to disease or genetic abnormalities. 3. most of the wood used for fuel comes from native forests around the world. the harvesting of wood for an energy source has serious environmental implications. identify the environmental concerns of harvesting wood. a) soil erosion b) cost of harvesting c) habitat destruction d) habitat destruction and soil erosion

Science27 of the most iconic, jaw-dropping photos of the earth and the moon from spacedave mosher  oct 1, 2018, 11: 13 am etnasa/flickrapollo 11 astronauts took this photo of earth on july 20, 1969.from the ground, earth looks like a boundless fertile plain that beckons to be explored and exploited.but astronauts would beg -  and even plead  - to differ."you realize that people often say, 'i hope to go to heaven when i die,'" jim lovell, an astronaut who flew on the apollo 8 and apollo 13 missions to the moon, previously  told business insider. "in reality, if you think about it, you go to heaven when you're born."lovell has seen first-hand that we live on a tiny rock hopelessly lost in the void. he's also quick to tell you it's the only one we've got - a  fragile spaceship  for more than 7 billion people: "you arrive on a planet that has the proper mass, has the gravity to contain water and an atmosphere, which are the very essentials for life. and you arrive on this planet that's orbiting a star just at the right distance - not too far to be too cold, or too close to be too hot - and just at the right distance to absorb that star's energy and then, with that energy, cause life to evolve here in the first place. in reality, you know, god has really given us a stage, just looking at where we were around the moon, a stage on which we perform. and how that play turns out is up to us, i guess."humanity has recorded photos of earth from hundreds, thousands, millions, and even billions of miles away, some of them taken by lovell himself.these images not only scientists study our dynamic world, but also understand how a habitable planet looks from afar, which aids the search for  more worlds. most importantly, however, the images underscore our peculiar existence on  a mote of cosmic dust.take a moment to ponder 27 of the most arresting images of earth that humankind has ever captured from space.a
