Orchids and the environment

    The orchid is a beautiful flower that can grow indoors or outdoors. There are over 25,000 different species of orchids, so it's one of the largest families of p{#blank#}1{#/blank#} in the world. Orchids can come in many different c{#blank#}2{#/blank#}as well, such as white, purple, pink, blue and yellow. There are several conditions that help orchids grow so well. Orchids need the right temperature, as well as the right amount of sunlight, soil, and water in order to l{#blank#}3{#/blank#}.

    F{#blank#}4{#/blank#} indoor orchids, it is much easier to control these conditions. For example, orchids usually need to be watered once a week, and you can control how much water you give to the plant. Also, many orchids grow best if they had indirect sunlight b{#blank#}5{#/blank#} direct sunlight will burn them. Indoor orchids can be placed near windows with curtains or blinds. This will protect them and give them the indirect sunlight they need.

    However, as to orchids that grow outdoors in the wild, global warming can become a threat. Unfortunately, global warming affects temperature, light and rain. All these factors will affect the way orchids live and grow. Most orchids will live c{#blank#}6{#/blank#} within a narrow temperature range of 18.3 to 23.8 degrees Celsius. Global warming can increase temperatures beyond the natural range for these flowers. Unfortunately, this can destroy orchids because they can't survive in hot, dry conditions. Second, air pollution can create acid rain. Acid rain is created when gases from fossil fuels combine with water in the air to form acids. When acid rain falls on plants and trees, it destroys the n{#blank#}7{#/blank#} balance of the soil and kills them.
