Not 100% but i think it'll cause the earth to rotate slightly slower, its definitely not the last one though
Answer:
When considering the environmental impact of a sewing machine, it is unlikely that this common household appliance immediately conjures images of ecological threat. However, the sewing machine plays a leading role in the fashion industry, which, according to a report by the Ellen MacArthur Foundation, is one of the largest sources of pollution in the world. The report suggests that the textile and fashion industries produce more pollution than aviation and international shipping combined.
Also, with the production of sewing machinery projected to exceed $7 billion this year in China alone, the distribution of those machines will have a massive impact on greenhouse gas emissions. The mass production and distribution of sewing machines, both industrial and domestic, also requires tons of packaging material which negatively impacts the environment. Lonely Whale and the Point Break Foundation estimate that by 2025 there will be one ton of plastic for every three tons of fish in the ocean. Even more alarming, the United Nations suggests that by 2050 there will be more plastic than fish.
Modern domestic sewing machines are made from plastics and polymers, which increases affordability. It also increases the likelihood that consumers will replace rather than repair, especially in the case of handheld sewing machines, which are a growing novelty. With sewing machines constituting an increasing proportion of the millions of tons of household appliances which end up in landfills, this also poses a significant environmental concern.

Answer:
( I SUGGEST THAT YOU READ EVERYTHING ) Hydropower does not pollute the water or the air. However, hydropower facilities can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area.
Explanation:
Nowadays, huge power generators are placed inside dams. Water flowing through the dams spin turbine blades (made from metal instead of leaves) which are connected to generators. Power is produced and is sent to homes and businesses. Hydropower is the most important and widely-used renewable source of energy. Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. Reservoirs and hydropower are often thought of as “clean energy” because they don't burn fossil fuels to produce electricity. Research released within the last year has confirmed that dams and reservoirs are a major source of greenhouse gas emissions driving climate change. Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions. In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply. There are numerous environmental consequences of damming water, flooding entire areas, creating massive reservoirs, changing water flow, blocking the natural course of rivers, and constructing power lines and roads. There are only a limited number of places where these power plants can be built. Hydroelectric power has many advantages: it produces very little pollution; it is affordable; and the plants are energy-efficient, require little maintenance and are easy to stop and start. Besides being inexpensive, nuclear power produces little air pollution or greenhouse gases and can be contained in a small space.
