PKG 381 #1 - Assignment Example Crisp vegetables were packed in sacks made of cotton and sisal and these are products which are recyclable (Guerrero 2013). They have longer lifespan and can be used again and again before disposal or recycling. When disposed, they decompose over a short period of time. Filtered water are mostly packed in plastic, these plastics take hundreds of years to break down when disposed and are also expensive to recycle. They pollute the environment widely and expose flora and fauna in danger. Plastics even cause death to animals which humans really depend on. Being difficult to recycle makes man to dispose them any how due to our laziness posing threat to our environment (Guerrero 2013). Pudding containers are also made of plastic though somehow light. Still, they threaten our environment since it’s a loss recycling them. They require good disposal but not dumping them anywhere since they take long to break down. Humans have the greatest part to play in the conservation of the environment. Their action determines our environment’s stability. Good practices should be put in place especially when it comes to products we use. There should be laws to help us manage our environment and avoid laziness (Guerrero 2013). With good practices towards environmental conservation, the organisms we depend on will be able to survive and in long run human life will be

Why Sir Isacc Newton is important Essay Example | Topics and Well Written Essays - 500 words

Why Sir Isacc Newton is important - Essay Example Newton contributed important concepts of science, such as in physics that surpassed other discoveries of his time. He discovered the forces of motions of people and objects in the world and universe that led to an understanding of the forces of nature (Kaminski 1). These forces are published in the books in the field of Physics. He described the motion of things and people using three major principles that are taught in the present and form basis for industrial activities. For instance, he showed that objects remain in their positions unless when moved, and would move in straight lines to the force applied. In addition, objects would offer would offer an equal and opposite reaction for every action force. Newton also discovered and explained the force of gravity that acts on all bodies and people. The force of gravity is very important since explains the solar systems and other items in the universe (Whipps 1). The force of gravity explains the movement of the earth and the moon, whi ch cause ocean water currents and as well as explaining bulging of the earth around the equator. He explained the importance of gravitational force in the movement of people by pulling them towards the center of the earth. He also enriched the field of physics through the developments of in movement of fluids as well as optics(Kaminski 1). Many optical substances and fluid flow systems in industries are based on his discoveries. He also developed a practical telescope as well as observed the multi-color properties of light using prisms. Newton also contributed to the other areas such as mathematics through development of important formula that are still applicable solving mathematical situations in the present (A&E 1). For instance, he laidthe foundation for the development of modern calculus and developed the formula for computing areas of curved or spherical objects that enabled solutions and breakthrough in mathematics.
